The Training Academy

The UNSC Training Academy is a recurring place throughout the series. It is owned by Captain Hemrix and was attended by King, Scout, Backlash, Gary, Oz, Vexus, Isaac, and Nathaniel.

In Season 3, the training academy becomes a sort of prison; holding all of the squads there and making them do slave labor. Towards the end of the season, Gold Squad rescues all of these squads and destroys a bit of the training academy in the process.
